What are scale inhibitors

Scale inhibitors are a type of chemical substance used to prevent scaling problems in water treatment systems. Different scale inhibitors have different components and functions, and common scale inhibitors include:

Phosphate: such as phosphate salts, polyphosphate, etc., can form soluble complexes by combining with hard substances to prevent the formation of hard scale such as calcium and magnesium salts.

Corrosion inhibitors: such as citric acid, nitrite, etc., react with the metal surface to form a protective film, slowing down the corrosion of the metal and the formation of scale pads.

Multifunctional agents: composite formulations such as corrosion and scale inhibitors, polymers, etc., have both corrosion and scale inhibiting effects, and can effectively control the formation of various scales.

Organic acids, such as acetic acid and benzoic acid, can prevent the deposition of metal scale by forming coordination complexes with metal ions.

Surfactants: such as certain non ionic or cationic surfactants, can reduce the surface tension of water and prevent the formation of scale layers.

The selection and use of scale inhibitors need to be determined based on specific water quality conditions, the design and operating conditions of the circulating water system, and specific treatment objectives. In practical applications, it is usually necessary to analyze the water quality of circulating water, understand the composition and properties of the water quality, select suitable scale inhibitors, and add them according to the dosage requirements.

It should be noted that different scale inhibitors HEDP may have certain applicability and limitations during use. Therefore, when selecting and using scale inhibitors, it is recommended to refer to the technical information and operating guidelines provided by the supplier, and follow the correct operating methods to ensure their effectiveness and safety.
